| Line fault at the outlet -- do I need an electrician? hilde45 OP269 posts 03-20-2020 7:26am @bryhifi I have a digital multimeter. I use it to test car batteries. I suppose I might use that, too, no? In any case, I can get the three prong outlet if necessary. The DMM will work just fine.1) Set the m... | |
| Surge protector vs wall debate for amps @lowrider57 The Wiremold strip shown in the Link you provided does not offer surge protection. It is strictly a plug strip.Jim . | |
| Beware of NAD M3 Fire Hazard pwb OP9 posts 03-15-2020 10:01am Thank you everyone for the useful information. I guess I will just have to take the loss and move on. I will never purchase an NAD product again. Anyone have a recommendation for a good integrated under 2k... | |
| Beware of NAD M3 Fire Hazard almarg9,445 posts 03-15-2020 11:20am I noticed the vent cap on the other cap did not look like it was affected by the event. It doesn’t look like there is any bulging in the top vent cover. Wouldn’t the shorting diode have affected that cap as we... | |
| Beware of NAD M3 Fire Hazard heaudio123 Said: Could be anything, but a shorted diode in the bridge passing AC and cooking the capacitor would be my guess. jea48 response: Wouldn’t that cause a high current load on the secondary winding of the toroid power transformer causing ... | |
| Beware of NAD M3 Fire Hazard https://ibb.co/T1VBM5G I’ve never seen the top vent of an electrolytic cap blown off like the one in the photo. That’s just plain scary! heaudio123 Said: Could be anything, but a shorted diode in the bridge passing AC and cooking the capacitor wou... | |
| Low hum from amp @ greh OP If you had said the hum sounded like 120Hz then that would indicate an electrolytic filter cap/s in the DC power supply.60Hz..... My first thought would be a ground loop hum, except where you said the hum doesn’t start until after 30 min... | |
| Beware of NAD M3 Fire Hazard Al, that amp has a lot crap in it! How long did it take for you to find the 3 fuses? pwb said: I took it to the NAD authorized repair facility and they said a faulty power supply caused the round cylinder ( not sure of part name) to explode round ... | |
| Beware of NAD M3 Fire Hazard @ pwb Odd the AC line safety fuse did not blow. The fuse should have blown protecting the unit from becoming a fire hazard. Is the AC Line fuse the original OEM fuse that came with the amp? If it is the original OEM fuse I suggest you contact NAD ... | |
| Low hum from amp greh OP131 posts 03-13-2020 5:42am My amp is a Manley Stingray.When I first power it up, the hum isn’t audible until I’m about 30 minutes into listening. When I first power it up, the hum isn’t audible until I’m about 30 minutes into listening... | |
| Lets talk dedicated lines @ danvignau Here is an older white paper for a circuit breaker. The trip curve/requirements for current manufactured Thermal-Magnetic (T-M) breaker are still the same. Note you can continuously load a T-M breaker to 100% of its’ handle rating and ... | |
| Lets talk dedicated lines kymanor118 posts 03-05-2020 9:23pm We all know the benefits of dedicated lines, so what is this all about? Best practices....Hopefully to better understand the type of branch circuit wiring used and the best method used for installing it... | |
| Voltage question @winoguy17 Just to be clear, you need to select a step down transformer (SDT) that best matches your wall AC mains voltage. Again you need to check your AC mains voltage at the wall outlet. If your mains voltage average is 120Vac or less then a... | |
| Silly question, but I’ll ask it anyway. @last_lemming Wouldn’t work for interconnects. There is only one conductor covered by a very high voltage rated insulation. You need two conductors for an interconnect. A supply and a return.Next problem the conductor is usually made of compressed... | |
| Lets talk dedicated lines Edit: Like MC, it contains an additional grounding conductor, although with this type of cable it is permissible to use the metal jacket as the safety grounding conductor, as required with isolated ground installations. Not exactly... The armor al... |
